On the other hand, if control unit 205 is judged and all placed object (step S301 is a "No") on charhing unit 201A and 201B, then at step S302, control unit 205 judges whether to have identified and is placed in a charging destination apparatus on the charhing unit.
For example, then another object is placed on another charhing unit, then identified the charging destination apparatus of first placement if the destination apparatus that will charge earlier places on the charhing unit.(step S302 is a "Yes") in this case handles and enter step S307, and communication unit 210 communicated by letter with this device.If placed two charging destination apparatus, then communication unit 210 receives replying from these two charging destination apparatus 300.Yet, owing to identified a charging destination apparatus 300, thereby the destination apparatus 300 that another can be charged is identified as the device of new placement.Therefore, can discern the destination apparatus 300 that respectively charges that is placed on these two charhing unit 201A and the 201B.
If do not identify any device (step S302 is a "No"), then at step S303, at first excitation coil 201, and stop excitation coil 202.At step S304, communication unit 210 is communicated by letter with device, whether receives electric power with interrogation winding 301.At this moment, communication unit 210 receives replying from two charging destination apparatus 300.Because excitation coil 201 only, thereby obviously, notifying its device that is receiving electric power is that coil 201 transmits the device of electric power to it.For this reason, can will notify its device that is receiving electric power to be identified as the device that is placed on the charhing unit 201A.
At step S305, excitation coil 202, and stop excitation coil 201.At step S306, communication unit 210 communicate by letter with charging destination apparatus 300, with inquiry charge destination apparatus 300 they whether receiving electric power.As mentioned above, notifying its device that is receiving electric power is that coil 202 transmits the device of electric power to it, thereby can discern the device that is placed on the charhing unit 201B.
Therefore, when finishing the identification of the charging destination apparatus that is placed on each charhing unit, control unit 205 begins to be used for each is installed the processing of charging.Control unit 205 is according to the information Control coil stimulating unit 206 and 207 that is obtained by communication unit 210, is suitable for electric power to each charging destination apparatus charging with transmission.
More than explanation is for the explanation that is used for discerning in the system that comprises a charging device 200 and two charge destination apparatus 300A and 300B as shown in Figure 1 the processing of charging destination apparatus.
For example, may there be situation shown in the charging system 100A among Fig. 4.In Fig. 4, except that charging device 200, portable phone 300A and digital camera 300B, also there be charging device 200A, portable phone 300C and 300E and the video camera 300D of similar in charging device 200.
If device 300C～300E be present in charging device 200 can with scope that these devices are communicated by letter in, then as described in Figure 3, equipment 300C～300E is to replying from the inquiry of communication unit 210.In addition, if just by charging device 200A to portable phone 300C and video camera 300D charging, then portable phone 300C and video camera 300D send replying that they just are being recharged.As a result, in can not recognition device 300A～300D which is placed on the charging device 200.
Therefore, in this exemplary embodiments, carry out identification according to the flow chart of Fig. 5 and handle, be placed in charging destination apparatus on the charging device 200 with identification.Processing by control unit 205 execution graphs 5.
When detecting unit 208 detects the variation of the voltage or the electric current of coil 201 and 202, and control unit 205 detects when having placed the charging destination apparatus in charhing unit 201A and 201B at least one, begins this handling process.
At step S501, whether control unit 205 exists the charging destination apparatus that can communicate by letter with communication unit 210 around judging.If there is not the charging destination apparatus (step S501 is a "No") that can communicate by letter on every side, then judging the device that is placed on the charging device 200 is not the charging destination apparatus, and finishes this processing.
At step S502, if the charging destination apparatus responds (step S501 is a "Yes") to this inquiry, then at step S502, control unit 205 judges whether to exist function class to be similar to the charging device of charging device 200 based on replying that communication unit 210 is received.If control unit 205 detects charging device, for example, the charging device 200A (step S502 is a "Yes") on every side among Fig. 4, then at step S503, the on-off mode adjustment of between charging device, charging.
The following describes charging on-off mode adjustment.
After detecting charging device, between charging device, adjust, to prevent that detecting the employed mode signal of the device that is placed on the charging device 200 in the described in the back processing repeats.In this case, carry out this adjustment, so that charging device 200 uses mode signal 701 shown in Figure 7, and charging device 200A uses mode signal 702 shown in Figure 7.
If there is no function class is similar to the charging device (step S502 is a "No") of charging device 200, then charging device 200 uses suitable mode signal 801 as shown in Figure 8.In Fig. 7 and 8, when signal becomes on, excitation coil 201 and 202.When signal becomes off, stop excitation coil 201 and 202.
At step S504, communication unit 210 beginnings are communicated by letter with the destination apparatus that charges around all.In Fig. 4, charging device 200 is communicated by letter with portable phone 300A, digital camera 300B, portable phone 300C, video camera 300D and portable phone 300E.At step S505, carry out the processing that is used to judge the device of being placed.
